Gaurav,
BQ24130 does not have battery detection. I plan to modify and test your circuit on the BQ24130 tomorrow. What was the exact issue with the BQ24105 that I need to watch out for?
The voltage at ISET pin sets the charge current. You can inject a…
Hi Jeff F
BQ24640 is use external FET
we found have BQ24130 use internal FET.
with this part, can we input 5V and charge for super cap 4.2 V ?
Please advise,
Part Number: BQ24195 Other Parts Discussed in Thread: BQ24130 Battery Charger team,
Our customer has designed a battery charge circuit based on the bq24195 for Li-Ion. In some of their applications, they want to change to use a 2S Super-Cap. I know we…
K.S.Rajan:
Please check BQ24130 to see if it can meet your requirement or not.

Also, there is an application note talking about using STAT pin to change the Lead acid battery charge voltage setting.
Using the bq24650 to Charge…
Juanjo,
I think you need battery voltage remote sensing. Please check whether BQ24130 can meet your requirement. The BAT pin senses the battery voltage instead of the SRN.
Have you look at switch mode chargers such as BQ24130, BQ24113A or bq24125?
The bq2057W is a linear regulator like the bq24004, but the device requires and external pass transistor and sense resistor. Yes it will support two series cells.
For a simple…

Hi Team,
Regarding the Absolute Maximum ratings of BQ24195 , the Max negative voltage of Vbus and SW pin is -2 V , while the others is -0.3V .
What is the reason for different negative volt…
